Holy guacamole, that is an impressive amount of detail. Do you ever sleep? :)

Hi Matt, wow that's a gorgeous plane illustration!

So what I was getting at there is not so much that you should export just the wheel, but rather that I could probably make the hidden line exporter do an initial pass that worked on objects individually with the whole canvas temporarily framed around just that object. That could then give objects better accuracy on an individual level and the limits of the canvas resolution being stretched across the full scene would only impact how objects interacted with other objects and not also gunk up a small object's own self occlusion.

It may be a fair chunk slower than the current exporter since it would be doing more work for each individual object but would it be accurate to say that even if the exporter was say 5-10 times slower than current it would save you time in the long run if it gave cleaner results on small objects within a larger overall scene?

An idea of time drawing this plane ?

Thats sounds like a good workaround. I assume the canvas size is calculated on what is visible?

I don't mind the speed hit, its always better than having to redraw things which didn't quite come out right. At the moment I barely have time to make a coffee let alone drink it when i export :-)

this illustration took about 3 weeks, big chunk of that time is searching for all the 3d parts in NX and exporting.

In the old days to do an airbrush job would be a bout 4 weeks but this is 100% accurate, down to the last rivet if I wanted, although i usually strip out a lot of fixings in something this big. And the bonus is I can add extra bits if need - just remember the viewing angles and export at same size and position and it slots right in.

Hi Matt,

Yes, it covers the same area as the shaded background image that you optionally generate on AI and PDF output.

I've got these improvements on my list now, I should be able to work on them once the current V4 bug list is cut down.
